In order for me to go out where I was going I had to go through a "mud area" it was just a bunch of water and the top 3" were mud but anyway I was very easy on gas and a light came on that reads "GEN" and im worried about what it is. Can u tell me what it means and what I should do please.

Hello,

The 'GEN' light refers to the generator/alternator. This light gets triggered when the battery is not getting adequate charge from the alternator.

It could be due to a bad alternator as well as faulty wiring.
First check to see the alternator output to the battery.

Here is a helpful video that shows how to test the alternator:

Check for any corrosion on the alternator cable. Look for any water damage or mud being on the connectors of the cable.
Clean if necessary.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
